一、引言《园林遗传育种学》是园林专业的一门重要专业基础课,是研究园林植物品种种选育原理和方法的科学。它的任务是根据园林植物的遗传变异的规律,研究园林植物的种质资源的选择和利用,选育出花卉的新品种并进行良种繁育。当然它的基础是遗传学,遗传学是研究生物遗传、变异规律及其原理与应用的一门科学。
I. INTRODUCTION The “Garden Genetics and Breeding” is an important professional basic course for the gardening profession. It is the science for studying the principles and methods of garden plant variety breeding. Its task is to study the selection and utilization of germplasm resources of garden plants according to the law of genetic variation of garden plants, and to select new varieties of flowers and conduct breeding of improved varieties. Of course, it is based on genetics, and genetics is a science that studies biological inheritance, variation laws and their principles and applications.
